Summary:
|
With the acceleration of digital transformation and cloud–network convergence, many organizations are transferring increasing volumes of data across wide-area networks (WANs). These transfer services could be called as elastic: they do not require strict real-time SLAs, particularly tight guarantees on per-packet latency or jitter, and they permit discontinuous (pause/resume) transfers; however, they are expected to complete a specified data volume within a specific time period. Currently, networks lack explicit mechanisms to assure transfers meet such completion time requirements; on the other hand, over-provisioning for transfer services may ensure strong guarantee but brings challenges of high costs and low elasticity. Meanwhile, operators’ networks exhibit idle resources that vary over time and across different links and nodes. These idle network resources can be harnessed to serve such transfer services, improving resource utilization and reducing transfer costs, thereby benefiting both network operators and users. Therefore, related network capabilities need to be enhanced to enable dynamic awareness, control, and scheduling of idle network resources and transfer services, ensuring that transfers are completed within the required time windows while improving overall network efficiency.
This Recommendation specifies the requirements, framework, and procedure of next-generation network evolution to support elastic transfer services and overall optimization. It focuses on fine-grained resource awareness and allocation, dynamic transfer scheduling, and related optimizations to provide completion-time-assured transfer capabilities and transfer optimization mechanisms. This Recommendation helps reduce over-provisioning and transfer costs, enhance resource utilization, and support on-time completion of transfer services.
